Benefits:

Slotted or drilled rotors prevent glazing of the pads, add bite and improve wet and dry braking performance. PowerSlot Slotted and StopTech's SportStop rotors have a durable black coating on the non-swept areas of the rotor to prevent unsightly corrosion. Stainless steel brake lines improve pedal feel and reduce the amount of time between applied pedal pressure and actual deceleration by preventing expansion, which stock rubber flex lines allow. High performance street pads provide you with higher resistance to fade, higher maximum operating temperature, and better initial bite to allow consistent deep braking into corners. Good for street and autocross. Not for extended track sessions.

For extended track sessions, or if you are running out of heat capacity with your current stock sized upgrade and/or having to replace pads and rotors often, you may want to consider investing in the added heat capacity that a Big Brake Kit offers.
